On melting of ice , there is a decrease in volume instead of increase . Why ?

Because of the crystal structure of the ice, ice has lower density than liquid water. So the volume of the ice of same mass is greater than water. When melting, the volume will decrease.

nignag [31]

In the given case, the scientist should use a circle graph or pie chart.  

One can dissect a circle into smaller segments, a component of the circle is known as an arc and an arc is named on the basis of its angle. A pie chart, or a circle graph, is used to visualize data and information.  

A circle graph is generally used to demonstrate the outcomes of an examination in a proportional way. In a circle graph, the arcs are proportional to how many percents of the population gave a particular answer.

erica [24]

Answer:

1) conduction

2) Radiation

Explanation:

Conduction is a mode of heat transfer by which heat energy is transferred through a material, the average position of the particles of the material remaining the same.

Radiation is a process of heat transfer by which heat is transferred from a hotter to a cooler point without any intervening medium.

The pan used to fry the egg is a conductor of heat hence heat can pass through it by conduction thereby enabling the eggs to cook.

Heat can travel without an intervening medium hence Zoe feels hot near the stove. This ability of the heat to travel without an intervening medium is called radiation.

Nuclear decay<br>27Al + He 》 39P<br>​
dybincka [34]

Answer:

_{13}^{27}\text{Al} + \rm _{2}^{4}\text{He} \longrightarrow \, _{15}^{31}\text{P}

Explanation:

The unbalanced nuclear equation is

^{27}\text{Al} + \rm \text{He} \longrightarrow \, ^{31}\text{P}

We can insert the subscripts, because these are the atomic numbers of the elements

_{13}^{27}\text{Al} + \, \rm _{2}\text{He} \longrightarrow \, _{15}^{31}\text{P}

That leaves only the superscript of He to be determined,

The main point to remember in balancing nuclear equations is that the sums of the superscripts must be the same on each side of the equation.  

Then

27 + x = 31, so x = 31 - 27 = 4

Then, your nuclear equation becomes

_{13}^{27}\text{Al} + \, \rm _{2}^{4}\text{He} \longrightarrow \, _{15}^{31}\text{P}

Murrr4er [49]
<span>NaCl is poster-compound for ionic bonding. The bonds in NaCl have about 70% ionic character, making the bond highly polar. its overstatement to state that there is actual ion in NaCl with +1 and -1 charge but actual charge of Na and Cl is +1 and -1 ion, since Nacl exist as a network of highly charged particle and not discrete molecule, NaCl particle does not exhibit intermolecular forces. Water molecule on other hand exhibit London dispersion force, keesom force, and hydrogen bonding. The polar water molecule are attracted to the polarized Na and Cl atoms. This is what allow NaCl(s) to dissolve and ionize in water. Therefore type of attraction in NaCl is ion-dipole attraction.</span>
